Reference .new being had to theA details of the drawings by letter, A designates the frame of the machine, which is mounted upon suitable legs A', and B designates endless conveyers, there being four shown in the draw ings; but as many of the conveyors may oe employed as desired. Said conveyers are mounted upon the sprocket-wheels B and lpassover idlers B2, ing driven from the shaft B3, which is geared to any suitable driving mechanism.` i Each and at intervals along the chain are the lugs C', adapted to carry the ear ofcoru forward table C2.

table C2' is asectional .pair of disks 'of similar construction mounted adjacent to the end ofeach endless conveyor.

The inner face oeachof said disks D4 carries a rubber plate the diskswhich are arranged in pairs being positions diametrically opposite and as the disks vrotate to feed Mounted adjacent to the inner end of each" trough in which an endless 'eonveyer is mounted are the -two lseries of spreading-rollers d', which. are so positioned with relation to each other and m unted upon suitable bearing-'rods that as se tions of the disks come'adjacent to theear of corn they will the thrown laterally or away from eachother in order Vance upon ,the table U2 gripped by the sections as they' pass by said antifriction-rolle andare thrown, by means of the springs, against the ear of corn.

a pinion-wheel F' tixed to rotate therewith, and a spring Fzis mounted upon said 'shaft and disposed intermediate one of the standards A2 and the hub of the pinion-wheel F' and adapted to normally hold said pinionwheel in a position at its farthest throw toward the con veyers or in the position shown in Fig. l of the drawings. Saidpiuiou-wheel is in mesh with an elongated pinion-wheel F3,` which is fixed to rotate with the shaft F4, which is jourualed in said standards A2. The shaft Ff has a sprocketwheel F5, which is drivenby means of sprocket-chain connections F6 with the shaft F7, mounted upon and rotating withthe shaft FS. Mounted upon the inner end of the shaft 'F is a collar' G, having two flexible arms G' bearing thereon, said arms being pivoted at points g to lugs which are mounted upon the cup H. Said cup, a'n enlarged detail view in section being shown in Fig. 5 of the drawings, has a spring H interposed between the cup and said collar or hub G, and at the outer ends 'of the arms G' are the adjustable bars H2, which are held in adjusted positions by means of the thumb-screws Il Connected to the ends .of said bars H2 are the cuttingknives K, an enlarged detail View of one of said knives being shown in Fig. 7 of the drawings. Said knives have scalloped cutting edges K' and have elongated slots K2, which are adapted to receive the pins K3, carried by the slotted bar K4, which is fastened to the. outer en,- larged-'end of saidcup H. The inner cutting vends of said knives project vat locations diarnetrically opposite through slots'in the shell Kiand are adapted to out the husksod an ear which is held oy the disks in said shell and as the latter rotates.v H3 designates an apertured partition in said cup H'having an annular liange H4 about its centrai aperture and a cuttingknife H5 fastened to the inner face of said partition, its .cutting edge projecting over the margin of said central aperture for the purpose of cutting off the end of an ear of corn as it is inserted through said l aperture.

Mounted upon a shaft L is apair of sectional disks L', which are similar in construction to the disks D, before described, and each disk as itpasses by the plate`J2is thrown outward spreading-rollers J3, which eferred to, and M designates a cup, W M -4s,simil: ir to the cup H, with similar attachments consisting of the cutting-knives the arms M2 and provided w lgnife M3 forcutting off the opposite end of the ear, said cup being yield- Aplatform N',

ingly held upon the hub ,M47 which is iixed to rotate with the shaft lM5 and is driven by geared connection with the pinion-wheel M6. Mounted underneaththe shaft L is a. guideplate ,N, and underneath said plate N is a on which the ear of corn falls after the two ends thereof have been'cut 0E and the husks severed preparatory tothe passage of the ear between the vertically-disposedV brushes O, there being two of said brushes positioned near together and between which` vthe ear of corn is adapted to pass before passing between the disks P, there being two of the latter, which are fixed to rotate with the shaft Pand have the rubber plates thereon similar to those described upon the disk D. Journaled in-suitable bearings in the frame are the shafts Q, which havebevel-wheels Q', with their ends geared to the wheels Q2, mounted on a shaft which is geared torthe shaft L by means of a'sprocket-chain Q3. Rotating with eachof said shafts Q is-'a cylinder Q4, having spikes Q5 about its circumference whichare provided forthe purpose oflooseuing the husks from the ear of corn as the ear is fed over the same by the disks P, the husks as they are severed from the ears adapted to pass between two'rollers which are positioned adjacent to each other. Depending from a beam R, forming a part of theframe of the machine, are the two brushes R', similar to the brushes O, before described,`and between which brushesMwhich are concaved, the ear is fed by the rotary disks P. vJournaled upon a shaft R2 are thedis'ks R3, which have theirv inner faces formed into brushes adapted to` brushagainst the ears of corn as they are advanced by the disks over the rollers Q4. Mount-ed within the sprocket-wheel R4, which is mounteddipon suitable ball-bearings, a detail of which is shown in Fig. 6 of the drawings and in side elevation in Fig. 1, are the two concaved brushes R5, which are pivotally mounted and heldV yieldingly by means of the springs R6. Said sprocket-'wheel R4, which is mounted in suitable bearings, has a sprocket-chain Ri, gear-Whee1R9, fixed to rotate with theshaft F4. Said brushes R5 are so positioned .with relation to the disks R3 thatas the ear of corn is advanced by said disks it will be fed through between the rotary brushes, which have a tendency to loosen any. silkor remaining husks that may be upon thegear, and as the ear passes by said rbrushes itis caught bythe disks S,' which have bristles upon the inner faces and which are mounted upon the shaft S', driven by geared connection with the main operating-shaft, and Tdesignates a. pair of depending brushes similar to the brushes R', through which the ear passes afteremerging from the disks S. yUnderneath the disks S are-the rollers W, over which the ears pass andv between which any silk or husks pass that .are stripped from the ear as it passes through the apparatus, and directly underneath the last pair of brushes Pis a chute V,

IOO

which passes about a `of the husks and the into which the ear falls after being relieved silk.

nthei'pre'sent machine I have shown-four t InA operation the ears" of corn are placed ear, which upon the conveyors and deposited from the C2, where they are same upon the platforms gripped at positions diametrioally opposite by the yielding sections of the disks D. `As the disks revolve, the earsare fed forward intothe open-end of the cup H, which is rorating rapid-ly by 'gearedconnection with the main operatingshaft, and as the ear enters said cup the end of the through the aperture in the partition H3 is severed and the husks are cut by means of the knives K a short distance in from the end of the ear. A`s the knives are rotating rapidly they perform their work without retarding the movementof the rear end of the after its forward end has been cut off is pulled down by the frictional gripping ofthe-disks D, and the motion of the ear is reversed and is fed with the uncut end into the passage-way between the disks D, and

when driven to its limit by means of the disks D the uncut end of the ear is frictionally rripped by the disks L and fed into the s econd cup M, Where the same operation is repeated as in cutting the opposite end, and at this stage of the operation of the machine the line of travel of the ear is again reversed and the ear fed by the disks L into the passageway between the table Nl and the guide N and is pushed, by means of the disks L' still fricH tienally engaging the ear,betwe`enthe brushes O. As the ear passes between the brushes it is gripped by the frietional disksT and is advanced over the spur-rollers Q5, where the husks are removed from Vthe ear, after which the ear passes between the brushes R', is again engaged and acted upon by the disks R3, which have brush-surfaces, is passed between the rotary brushes R5, thence "acted upon by the disks S preparatoryY to its final passage between the brushes T,which operation has a tendency to cut both ends of the ear and sever and remove the husks and silk which clings to the kernels after the husks are removed.
